A face modeling method and apparatus, an electronic device and a computer-readable medium. Said method comprises: acquiring multiple depth images, the multiple depth images being obtained by photographing a target face at different irradiation angles; performing alignment processing on the multiple depth images to obtain a target point cloud image; using the target point cloud image to construct a three-dimensional model of the target face. The present disclosure alleviates the technical problems of poor robustness and low precision of the three-dimensional model constructed according to the three-dimensional model constructing method.

Disclosed are an image processing method and apparatus, and an image processing device. According to the image processing method and apparatus, and the image processing device, an infrared binocular camera collects images formed when a measured object is illuminated by a speckle pattern projected by a projection assembly to obtain a first image collected by a first camera and a second image collected by a second camera; and three-dimensional data of the measured object is determined according to a pair of images constituted by the first image and the second image. By means of the method, three-dimensional data of a measured object can be relatively accurately obtained through measurement, thereby improving precision and accuracy of measurement, and also precision requirements for a projection assembly are low, so that costs can be lowered.
